Meteorite Gemstone Beads

Frequently asked questions

• What is a meteorite bead made of?

  Meteorite beads in the bead trade are almost always cut from iron meteorites — an iron-nickel alloy that formed in the metallic cores of asteroids that broke up billions of years ago, then fell to Earth at known impact sites thousands to millions of years ago. The two principal minerals in iron meteorite are kamacite (iron-rich) and taenite (nickel-rich), which interlock in the characteristic crystalline Widmanstätten pattern revealed by polishing and acid-etching the bead surface.
• How can I tell if a meteorite bead is real?

  The reliable visual test is the Widmanstätten pattern — interlocking crystalline bands of kamacite and taenite, geometric and irregular, revealed by a nital (dilute nitric acid) etch on the polished surface. The pattern forms during millions of years of cooling in space and cannot be reproduced in terrestrial steel. Hematite shows no pattern; terahertz composite shows uniform engineered banding; plain steel shows no pattern. Provenance — the named fall, such as Gibeon, Muonionalusta, or Campo del Cielo — should be disclosed; ask before buying if the fall isn't specified.
• Where does meteorite come from?

  The three major iron meteorites in the bead trade are Gibeon (Namibia, recovered since the 1830s from a fall roughly 30,000 years ago), Muonionalusta (northern Sweden, recovered since 1906 from a fall roughly 1 million years ago), and Campo del Cielo (Argentina, recovered since the 1570s from a fall roughly 4,500 years ago). Each fall has its own aesthetic register and finite supply — material is recovered from a known impact site, not mined from an ongoing deposit. Named-fall provenance should be disclosed where known.
• Will meteorite beads rust?

  Iron meteorite is an iron-nickel alloy and can oxidize if exposed to humidity, salt, sweat, or chlorinated water over time. Most meteorite beads in the trade are stabilized with a clear protective coating — lacquer, clear plating, or similar surface treatment — applied after the etching process to seal the iron from atmospheric moisture while preserving the visible Widmanstätten pattern. With reasonable care (wipe dry after wear, avoid prolonged moisture, store with a desiccant in humid climates), coated meteorite beads remain stable for years. Coating status should be disclosed; ask before buying if it isn't specified.
• How should I care for meteorite jewelry?

  Wipe with a soft dry cloth after wear; avoid prolonged moisture; store with a desiccant pack in humid climates. Avoid ultrasonic cleaning, steam cleaning, chlorinated water, salt water, and direct contact with perfumes or lotions — all can compromise the protective coating and expose the iron underneath. Meteorite is also relatively soft (Mohs around 4–5), so it can scratch against harder beads on the same strand; pair thoughtfully on mixed-stone designs.
